Effectiveness of Virtual Reality for Pain Relief in Procedures Related to Obstetrics and Gynaecology: A Systematic Review and Meta‐Analysis of Randomised Controlled Trials

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Background Immersive virtual reality (VR) technology offers a non‐invasive, non‐pharmacological approach to reduce pain perception in patients undergoing diagnostic or interventional procedures. Objective To systematically evaluate the efficacy of immersive VR technology in reducing pain perception during obstetric and gynaecological ...

Are There Higher Electron Densities in Narrow Emission Line Regions of Type-1 AGNs than in Type-2 AGNs?

The Astrophysical Journal
In the manuscript, we check properties of electron densities n _e traced by flux ratio R _sii of [S ii ] λ 6716 Å to [S ii ] λ 6731 Å in narrow emission line regions (NLRs) between Type-1 active galactic nucleus (AGN) and Type-2 AGN in SDSS Data Release ...

The Host Galaxy Fluxes of Active Galaxy Nuclei Are Generally Overestimated by the Flux Variation Gradient Method

Universe
In terms of the variable nature of normal active galaxy nuclei (AGN) and luminous quasars, a so-called flux variation gradient (FVG) method has been widely utilized to estimate the underlying non-variable host galaxy fluxes.

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

Integrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

Broad-line Regions behind Haze: The Intrinsic Shape of the Brγ Line and Its Origin in a Type 1 Seyfert Galaxy

The Astrophysical Journal
The broad-line region (BLR) of active galactic nuclei is an essential component, yet its small size keeps its origin, structure, and kinematics uncertain.

Galactic bars and active galactic nucleus fuelling in the second half of cosmic history

Astronomy & Astrophysics
We investigate the role of galactic bars in fuelling and triggering active galactic nuclei (AGN) in disc galaxies up to z ∼ 0.8. We utilised a deep learning model, fine-tuned on Galaxy Zoo volunteer classifications, to identify (strongly and weakly ...

Molecular Gas in the Powerful Radio Galaxies 3C~31 and 3C~264: Major or Minor Mergers?

, 2000
We report the detection of $^{12}$CO~($1 \to 0$) and $^{12}$CO~($2 \to 1$) emission from the central regions ($\lesssim 5$--$10 {\rm kpc}$) of the two powerful radio galaxies 3C~31 and 3C~264.

Out There No One Has a Right to Die

Bioethics, EarlyView.
ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...

Chemical enrichment in LINERs from MaNGA

Astronomy & Astrophysics
Context. Chemical abundance radial gradients provide key information on how the processes that affect chemical enrichment of the gas-phase interstellar medium (ISM) act at different galaxy scales. In the past decades, though there has been an increase in

The hard X-ray view of bright infrared galaxies

, 2009
Aims. The synthesis of the cosmic X-ray background (CXB) requires a large population of Compton-thick active galactic nuclei that have not been detected so far.
